Zusammenfassung:Using pure samples of alpha -Sr...CrO..., an antiferromagnetic (AF) transition was first detected at T... = 112 K by magnetic susceptibility and specific heat measurements. In addition, another transition was observed at T... = 140 K with a clear peak in the specific heat and a small enhancement in the magnetic susceptibility. Despite the two-dimensional crystal structure, the magnetic susceptibility at higher temperatures almost obeys the Curie-Weiss law down to T... These properties are similar to those of alpha -Sr...VO... Electrical resistivity clearly indicates the insulating nature with an electronic band gap of \(\Delta \simeq 1150\) K.
