Title

Chemical-Pressure Tailoring of Low-Field, Room-Temperature Magnetoresistance in (Ca, Sr, Ba)Fe0.5Mo0.5O3

Abstract

Chemical pressure effects of low-field intergrain magnetoresistance (IMR) in (Ca,Sr,Ba)Fe0.5M00.5O3 were studied by doping either Ba or Ca into the Sr site (IMR) was found to be highly tunable. The Curie temperature and magnetic softness were changed due to the chemical pressure exerted by the dopant. The room temperature IMR was reported to be 3.5% in 100 Oe at optimal doping.
