“…The mechanism of enchancing MO properties by adding LRE ( Pr,Sm,Nd) elements to HRE-TM amorphous alloy films has been proved in experiment and theory in our previous work [4,5]. Here, we prepared LRE-HRE-FeCo / HRE-FeCo couple-bilayered by rf 110 magnetron sputtering (LRE=Pr,Nd,Sm; HRE=Tb,Dy).…”

Abstract-In this paper, the temperature dependence of magnetic and magneto-optic (MO) properties of light rare earth (LRE)-heavy rare earth (HRE)-FeCo / HRE-FeCo has been investigated. The shapes of Kerr hysteresis loops were lead to great changes as temperature varied. The Kerr angles of couple-bilayeredfilms were shown different decreasing tendency as compared to those of single-layered films when temperature was increased. It was found that the exchange-coupled action has a profundly contribution to Kerr angles through the temperature range(-30 0 -1 lOt).

Abstract-An exchange-coupled double-layered (ECDL) films used as enhancement of Kerr effect has been reported. It was found that the Kerr hysteresis loop of the ECDL films has shown different shapes of hysteresis loops as compared with that of single layered films. In general, "stages" was appeared in the Kerr hysteresis loop of ECDL films. The enhancement of Kerr effect was considered to be the result of exchange-coupled action between the boundaries of two layers, which was relative with the boundary domain walls. A model for magneto-optic (MO) Kerr hysteresis of ECDL films was established. Theoretical calculation for coercivity and Kerr angles of couple-bilayered films were well agreed with the experimental results.
