Abstract

AbstractWell‐characterized bulk materials in the candidate dilute magnetic semiconductor system In2 − xCrxO3 are prepared for 0 ≤ x < 0.15, with cation site preferences in the bixbyite structure identified by diffraction methods. Small ferromagnetic moments are observed; their size (<10−2 µB/dopant ion) is not consistent with bulk ferromagnetism. The resulting bulk materials display dilute paramagnetic behaviour, with all of the moment expected per Cr3+ cation dopant being involved in this paramagnetic response.
