Electronic Properties and the Lattice Instability of Laves-Phase ZrV sub 2

Electronic Properties and the Lattice Instability of Laves-Phase ZrV sub 2

Pure, perfect, single-crystal ZrV sub 2 does not undergo a structural phase transformation but all other sample modifications, including twinned single crystal, do transform ( approx 100 deg K) from the cubic to a rhombohedral phase. All samples exhibit, in addition, an electronic instability (also...

Zusammenfassung:Pure, perfect, single-crystal ZrV sub 2 does not undergo a structural phase transformation but all other sample modifications, including twinned single crystal, do transform ( approx 100 deg K) from the cubic to a rhombohedral phase. All samples exhibit, in addition, an electronic instability (also approx 100 deg K). An anomaly in the ultrasonic velocity occurs at higher temp. ( approx 150-180 deg K) for pure polycrystalline ZrV sub 2 samples.28 refs.--AA
