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 Sm1-xErxFeO3.
