FIG. 1.

Zero-field-cooled and field-cooled dc magnetization versus temperature for low magnetic field (20 Oe and 50 Oe): (a) parent SrCoO2.88, (b) partially oxidized SrCoO2.96, (c) fully oxidized/stoichiometric SrCoO3, and (d) partially reduced SrCoOx (x < 2.88).

FIG. 2.

(Color online) High resolution XRD scans for the partially oxidized SrCoO2.96 sample: (a) wide range scan shows one psuedo-cubic phase, (b) expanded view of the tetragonally split (200)/(020) peaks from the (002) peak, and (c) expanded view of the single (222) peak. The peak positions for SrCoO2.88 and SrCoO3 are also shown for reference.

FIG. 3.

(Color online) Magnetic phase diagram for SrCoOx (2.5 ≤ x ≤ 3) showing the existence of (four) magnetic line phases at x = 2.5, 2.75, 2.88, and 3. Region I is the coexistence of two crystalline phases:7,8 orthorhombic SrCoO2.5, which is antiferromagnetic with TN = 570 K,6 and cubic SrCoO2.75, which is ferromagnetic with TC = 160 K (this work). Region III has just one crystalline phase; however, there are two magnetic phases with TC = 220 K and 280 K which are characteristic of SrCoO2.88 and SrCoO3, respectively. Region II has yet to be explored.
