【摘要】 Textured Bi and MnBi/Bi thin films are prepared by the pulsed laser deposition method.The highly c-axis textured MnBi films are obtained by annealing the bilayer consisting of textured Bi and Mn Elms.The coercivities of the MnBi/Bi film are 1.5T and 2.35 T at room temperature and at 373 K,respectively,showing a positive temperature coefficient.MicrostructuraJ investigations show that the textured MnBi film results from the orientated growth induced by the textured Bi under-layer.
