Abstract

Rare earth orthoferrite (R-FeO₃, R : rare-earth element) has spin reorientation phase transition (SRPT) at specific temperature and SRPT temperature can be controlled by mixing two different types of R-FeO₃. Through the observation of two magnetic resonance modes change by terahertz time domain spectroscopy (THz-TDS), we succeeded in observing SRPT which occurs at 480 K for SmFeO₃ and controlling the SRPT temperature for around room temperature (~310 K) in Sm_1-xEr_xFeO₃.
