Sf. Karmanenko et al., Dispersion characteristics of magnetostatic waves propagating at a ferrite/perovskite interface, TECH PHYS L, 26(10), 2000, pp. 923-925
The propagation of magnetostatic waves at the interface between an yttrium-
iron-garnet (YIG) film and a layer of perovskite compound LaAlO3, SrTiO3, o
r YBa2Cu3O7-x (YBCO) was experimentally studied. The microwave dispersion c
haracteristics were measured at room temperature and at 77 K. An effective
method for controlling the propagation speed and the phaseshift of magnetos
tatic waves in the YIG/YBCO structures is suggested. Specifically, the phas
eshift at 3 GHz is changed by more than 1.5 pi by reducing the critical cur
rent density from 1 to 0.7 x 10(6) A/cm(2). (C) 2000 MAIK "Nauka / Interper
