M\"ossbauer-effect measurements on ${\mathrm{Al}}_{86}$${(}^{57}$${\mathrm{Fe}}_{0.02}$${\mathrm{Mn}}_{0.}$ 98)g14 in the icosahedral phase indicate a distribution of quadrupole-splitting magnitudes at the iron sites. This distribution strongly indic

Amorphous MnSi is a concentrated spin-glass. In order to understand the underlying reason, the following similar systems were investigated: ${\mathrm{Mn}}_{3}$${\mathrm{Ge}}_{2}$, MnGe, MnC, MnAs, and MnSb. In the case of MnAs and MnSb which are stro

From a measurement and analysis of the extended fine structure on the Ge $K$-shell absorption cross section, we determine that the metalloid (Ge) nearest-neighbor environments in arc-quenched glassy ${\mathrm{Pd}}_{78}$${\mathrm{Ge}}_{22}$ and in spu

Using the picosecond pump and probe technique we have detected oscillations of photoinduced transmission and reflection in thin films of $a$-${\mathrm{As}}_{2}$${\mathrm{Te}}_{3}$ and cis-polyacetylene. These oscillations are due to the generation an

Quenched Ni-Mn alloys exhibit both a spin-glass state and ferromagnetism for Mn concentrations (${c}_{\mathrm{MN}}$) below 26 at.%. While previous studies concentrated on understanding various aspects of the magnetic properties (hysteresis, field coo

What could possibly be new in MnO 46 years after the discovery of its antiferromagnetic transition?: a spin-glass transition in the (25-50)-K temperature range. The susceptibility of MnO powders obtained by various treatments (MnO aged 30 years in am

The coherence distance (${\ensuremath{\xi}}_{0}$) of the pure type-I superconductors (Al, Pb, and Sn) was measured using the proximity effect with a ferromagnetic Ni film. The experimental values of ${\ensuremath{\xi}}_{0}$ for Al, Pb, and Sn, which
