Abstract

Three families of NixZry (x = 28, 36, 38, x + y = 100%) metallic glasses were prepared and examined using X-ray, temperature dependent transport and magnetic field. X-ray characterization shows characteristic diffuse spectrum, except for narrow regions of control samples, where partial crystallization was induced in finite small volumes. Magnetic properties confirm spin-fluctuating paramagnetic-like behavior, which we asses from preliminary Hall coefficient measurements, which is quantitatively different in three sample families. Temperature dependent AC and DC transport measurements were conducted in a broad temperature range from 70 K to 700 K, finding both quantitative and semi-qualitative differences between samples with different Ni/Zr ratio.
