We describe a minimal model for metamagnetism, based on a quantum spin Hamiltonian with a single energy scale. Within this model, the metamagnetic critical field is proportional to the temperature ...

The leading order nonlinear (NL) susceptibility, χ3, in a paramagnet is negative and diverges as T → 0. This divergence is destroyed when spins correlate and the NL response provides unique insights into magnetic order. Dimensionality, exchange in

Strongly correlated electronic systems can harbor a rich variety of quantum spin states. Understanding and controlling such spin states in quantum materials is of great current interest. Focusing on the simple binary system UPt3 with ultrasound (US)

We report measurements of the third order, ${\ensuremath{\chi}}_{3}$, and fifth order, ${\ensuremath{\chi}}_{5}$, susceptibilities in an itinerant oxide metamagnet, ${\mathrm{Sr}}_{3}{\mathrm{Ru}}_{2}{\mathrm{O}}_{7}$, for magnetic fields both parall

We report here low temperature magnetization isotherms for the single molecule magnet, $(UO_2-L)_3$. By analyzing the low temperature magnetization in terms of $M= X_1*B + X_3*B^3$ we extract the linear susceptibility $X_1$ and the leading order nonl

We present a data-driven approach to predict entropy changes (ΔS) in small magnetic fields in single-molecule magnets (SMMs) relevant to their application as magnetocaloric refrigerants. We construct a database of SMMs with a representation scheme i

Calculations of the ability of titanium–ethylene complexes of the type, Ti:C2H4, to absorb molecular hydrogen have been performed using density functional theory. A maximum of 5H2 molecules can be adsorbed on Ti:C2H4 thereby giving an uptake capaci

Utilizing pulsed laser ablation we show that it is possible to grow isolated nanostructures of vanadium whose shape and size are controllable simply by changing the background pressure of an inert gas in the growth chamber. The nanostructures obtaine
