LOW TEMPERATURE MAGNETIC BEHAVIOR OF NI-FE-AL-B SHAPE MEMORY ALLOYS - MAGNETIC SUSCEPTIBILITY AND MOSSBAUER SPECTRA

Magnetic susceptibility measurements and Mossbauer spectra (MS) were performed on a series of Ni x Fe y Al z B shape memory ribbons obtained by a melt spinning technique. The MS at room temperature show quadrupole splittings of two iron sites. At low temperatures (T
