Anomalous transport in itinerant metamagnets with structural disorder
We report on low-temperature transport in magnetic conductors with structural disorder. The primary motivation for this work was large positive magnetoresistance (MR) found in magnetically ordered ground state of some itinerant metamagnetic alloys. The positive MR suggests that external magnetic fie...
