Frustrated Gd3+ Double Perovskites as High-Performance Magnetocaloric Materials for Sub-100 mK Adiabatic Demagnetization Refrigeration
Tim Treu, Marvin Klinger, Christian Heil +6
Achieving temperatures below 100 mK is essential for advancing quantum technologies and exploring fundamental quantum phenomena. While paramagnetic salts have traditionally enabled…
Sub 1 K Adiabatic Demagnetization Refrigeration with Rare-Earth Borates BaXBO and BaXBO, 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 NaGdPO
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 NaGdPO$_…
Utilizing frustration in Gd- and Yb-based oxides for milli-Kelvin adiabatic demagnetization refrigeration
Tim Treu, Marvin Klinger, Noah Oefele +3
The manifold of energetically degenerate configurations arising from competing interactions in frustrated magnets gives rise to an enhanced entropy at lowest temperatures, which ca…
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 through magnetiza…
Intermediate field-induced phase of the honeycomb magnet BaCo(AsO)
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…
Cooperative quantum tunneling of the magnetization in Fe-doped LiN
M. Fix, J. H. Atkinson, F. Müller +2
The spin-reversal in dilute Li(LiFe)N with % is dominated by resonant quantum tunneling of spatially well-separated states. We report on the effect of fin…
Frustration on a centred pyrochlore lattice in metal-organic frameworks
Rajah Nutakki, Richard Röß-Ohlenroth, Dirk Volkmer +6
Geometric frustration inhibits magnetic systems from ordering, opening a window to unconventional phases of matter. The paradigmatic frustrated lattice in three dimensions to host…
LiSr[MnN]: a magnetically ordered, metallic nitride
F. Hirschberger, T. J. Ballé, C. Haas +5
LiSr[MnN] single crystals were successfully grown out of Li rich flux. The crystal structure was determined by single crystal X-ray diffraction and revealed almost linear $…
Frustrated magnet for adiabatic demagnetization cooling to milli-Kelvin temperatures
Y. Tokiwa, S. Bachus, K. Kavita +3
Generation of very low temperatures has been crucially important for applications and fundamental research, as low-temperature quantum coherence enables operation of quantum comput…
Strain induced changes of electronic properties of B-site ordered double perovskite SrCoIrO thin films
S. Esser, C. F. Chang, C. -Y. Kuo +10
B-site ordered thin films of double perovskite SrCoIrO were epitaxially grown by a metal-organic aerosol deposition technique on various substrates, actuating different str…
