Abstract:
Recent discoveries of novel physics in two-dimensional (2D) magnetic materials have sparked the search of new layered magnetic semiconductors. Compared to the traditional inorganic 2D van der Waals crystals, hybrid organic–inorganic metal–halide frameworks offer significantly enhanced chemical and structural versatility, where their optical, electronic, and magnetic properties can be readily modulated with both organic and inorganic components. Here, we reported a series of new Fe–Cl-based layered double perovskites LnMIMIIICl8, [n = 4, L = phenylethylammonium or chiral R-(+)-β-methylphenethylammonium and n = 2, L = 1,4-butanediammonium; MI = Ag/Na; MIII = Fe/In]. UV–vis measurements show that their optical band gaps are highly tunable by varying the organic cations, MI ion, and MIII ion. Magnetic susceptibility measurements suggest an antiferromagnetic coupling between the nearest FeIII–FeIII, where the Curie–Weiss temperature, Néel temperature, and frustration factors can be easily modulated with their compositions and dimensionality. Our study demonstrates the rich and interesting magnetic properties in these layered transition-metal–halide double perovskites and paves the way for design of multifunctional magnetic materials.Keywords:

I consider the ground state of quantum spins interacting via Heisenberg antiferromagnetic exchange, in lattices having several types of local environment. In unfrustrated cases, when a Néel type order exists, it is known that quantum fluctuations are site-dependent, and lead to an inhomogeneous local staggered order parameter. This paper discusses some effects of adding frustration to such a system, by including next nearest neighbor antiferromagnetic interactions. Within linear spinwave theory, it is found that as the frustration parameter increases, the local order parameters decrease at a rate that depends on the type of sites involved in the frustrated loops. The cases of a decorated square lattice system, and of a quasiperiodic tiling are considered to study difierent ways in which antiferromagnetism is suppressed in these inhomogeneous systems.

Frustration tolerance affects survival ability directly.Therefore,frustration tolerance is premise of survival ability.Now,frustration tolerance of teenagers isn't strong enough.In order to improve their frustration tolerance and then strengthen their survival ability,we adopt methods as follows: first,face frustration in a proper way;second,analyze the problem calmly and find strategies;third,take active action and defeat frustration..

Frustration education is necessary in young students' overall education. Students should be taught to be mentally prepared for frustration, to have the courage to endure frustration, to have confidence in overcoming frustration and to be ready to answer the challenge of frustration.

The main types of frustration upon college students:learning frustration,ideal frustration,contact frustration and love frustration.The reasons for frustration are either subjective or objective.Therefore,strengthening frustration education should be carried out as follows:strengthening cognition frustration,heightening the ability of endurance and emotion relaxing.

Frustration situation and the college students' senses of frustration are always found among college students very easily and frequently in recent years. Therefore, it's very necessary to carry out antifrustration education and try to make them be lifted out of the puzzle of frustration, leap over the turning period smoothly and finish their studies. The research show that the frustrations of the college students may be divided into nine types: adaption frustration, learning frustration, interpersonal communication frustration, emotion frustration, love frustration, physiology frustration, family frustration, school frustration, graduation frustration etc. Some measure of preventing and adjusting may be provided in accodance with every type in the thesis to promoting the quality of frustration coping, strengthening frustration tolerance and realizing self-monitoring of frustrtion coping.

Failure,to primary school students,was anything but the mother of success,for the nega-tive influence of frustration is always greater than the positive.The sense of frustration is partly from students themselves and partly from the influence of schooling.

We studied the spin arrangement in ultrathin antiferromagnetic Mn films in contact with a ferromagnetic Fe(001) substrate using spin-polarized scanning tunneling microscopy. Mn shows a layerwise antiferromagnetic order on Fe(001). In regions where Mn overgrows Fe steps, a frustration of the antiferromagnetic order occurs which is similar to a 180 degrees domain wall. This topologically enforced frustration was studied as a function of Mn thickness. A linear increase of the width of the frustration region with the Mn thickness was found.
