Sub 1 K Adiabatic Demagnetization Refrigeration with Rare-Earth Borates Ba $_{3}$ XB $_{9}$ O $_{18}$ and Ba $_{3}$ XB $_{3}$ O $_{9}$ , X = (Yb, Gd)

Marvin Klinger, Tim Treu, Felix Kreisberger +4

Adiabatic demagnetization refrigeration (ADR) is regaining relevance for the refrigeration to temperatures below 1 K as global helium-3 supply is increasingly strained. While ADR a…

Adiabatic demagnetization refrigeration with antiferromagnetically ordered NaGdP $_{2}$ O $_{7}$

P. Telang, T. Treu, M. Klinger +3

We present a comprehensive study of the structural, magnetic, and thermodynamic properties, as well as the adiabatic demagnetization refrigeration (ADR) performance of NaGdP $_{2}$ O$_…

Cooperative quantum tunneling of the magnetization in Fe-doped Li $_{3}$ N

M. Fix, J. H. Atkinson, F. MÃ¼ller +2

The spin-reversal in dilute Li $_{2}$ (Li $_{1 - x}$ Fe $_{x}$ )N with $x < 1$ % is dominated by resonant quantum tunneling of spatially well-separated states. We report on the effect of fin…

Strong enhancement of magnetic coercivity induced by uniaxial stress

Bin Shen, Franziska Breitner, Philipp Gegenwart +1

The performance of permanent magnets is intricately tied to their magnetic hysteresis loop. In this study, we investigate the heavy-fermion ferromagnet CeAgSb $_{2}$ through magnetiza…

Intermediate field-induced phase of the honeycomb magnet BaCo $_{2}$ (AsO $_{4}$ ) $_{2}$

Prashanta K. Mukharjee, Bin Shen, Sebastian Erdmann +6

We use magnetometry, calorimetry, and high-resolution capacitive dilatometry, as well as single-crystal neutron diffraction to explore temperature-field phase diagram of the anisot…
