Effects of Al micro-bumps on the magnetic properties and morphology of CoCrTa/Cr/Al thin films

CoCrTa thin films were deposited on glass substrates at various temperatures with or without Al micro-bumps. The coercivity of the CoCrTa thin films increased considerably by introducing the Al micro-bumps as a texture layer. The cause of the coercivity increase was attributed to the development of strong Co(10.
