An overview of quantum phase transitions (QPTs) in metallic ferromagnets, discussing both
experimental and theoretical aspects, is given. These QPTs can be classified with respect to …

In this paper, we review theoretical and experimental research on rare region effects at
quantum phase transitions in disordered itinerant electron systems. After summarizing a few …

We study the effects of quenched disorder in a class of quantum chains with (p+ 1)-multispin
interactions exhibiting a free fermionic spectrum, paying special attention to the case p= 2 …

Increasingly impressive demonstrations of voltage-controlled magnetism have been
achieved recently, highlighting potential for low-power data processing and storage …

Systematic spin-polarized density functional theory calculations were performed to
investigate the formation energies of native and substitutional anionic point defects in iron …

The magnetic spin ordering and the magnetization dynamics of a double perovskite Pr 2
CoFeO 6 have been investigated by employing the (dc and ac) magnetization and neutron …

These lecture notes give a pedagogical introduction to phase transitions in disordered
quantum systems and to the exotic Griffiths phases induced in their vicinity. We first review …

DC and AC magnetic measurements indicate the presence of multiple magnetic transitions
arising from the competing magnetic interaction between Cr and Mn in the perovskite La 2 …

Pyrite FeS2 has extraordinary potential as a low-cost, nontoxic, sustainable photovoltaic but
has underperformed dramatically in prior solar cells. The latter devices focus on …

Pyrite FeS2 has long been considered a potential earth-abundant low-cost photovoltaic
material for thin-film solar cells but has been plagued by low power conversion efficiencies …
