High frequency magnetic behavior through the magnetoimpedance effect in CoFeB/ (Ta, Ag, Cu) multilayered ferromagnetic thin films

We investigate the structural and magnetic properties and the magnetoimpedance effect of CoFeB/(Ta, Ag, Cu) multilayered thin films grown by magnetron sputtering. It is noticed that the peak of maximum magnetoim- pedance ratio values for a given frequency, as well as its position in frequency, is v...
