“…The photoluminescence spectra in high magnetic fields were recorded at KU Leuven Pulsed Field Facility. [ 81 ] In accordance with the experimental setup and to ensure relevant data an illustrative thermal range was selected (4.0–180.0 K). Briefly, a plastic cuvette with the sample was mounted into a cryostat surrounded by a pulsed field magnet.…”

Sensors are increasingly present in the everyday life in widespread technological applications, and engineering smart systems able to simultaneously detect different physical quantities represents a scientific challenge. Taking advantage of the molecular chemistry realm that offers the possibility to finely adjust physical properties, it is demonstrated herein that the luminescent single‐molecule magnet [Dy(acac)3(H2O)2]·H2O (acac = acetylacetonate) acts as a dual and synchronous thermometric/magnetic optical sensor in large ranges (10.0–180.0 K and up to ≈45 T) holding the promise to detect their variations in future devices.

“…Furthermore, we confirmed that the measured Hall voltage was directly proportional to the strength of the magnetic field. Magnetoresistance measurements were carried out between 10 and 250 K at the KU Leuven pulsed-magnetic field facilities [28]. Here, the current paths had the same dimensions as before and the current Table 1 Overview of the sputter-deposition parameters and average grain sizes of the three different types of AZO thin films, together with representative values of the room temperature resistivity r, the carrier concentration n, the carrier mobility m and the average optical transparency.…”

In this article, we report on the synthesis of thin, epitaxial films of the transparent conductive oxide Al:ZnO on (0001)‐oriented synthetic sapphire substrates by DC sputtering from targets with a nominal 1 at.% Al substitution. The deposition was carried out at an unusually low substrate temperature of only 250 °C in argon–oxygen mixtures as well as in pure argon. The impact of the process–gas composition on the morphology was analysed by transmission electron microscopy, revealing epitaxial growth in all the cases with a minor impact of the process parameters on the resulting grain sizes. The transport properties resistivity, Hall effect and magnetoresistance were studied in the range from 10 to 300 K in DC and pulsed magnetic fields up to 45 T. While the carrier density and mobility are widely temperature independent, we identified a low field–low temperature regime in which the magnetoresistance shows an anomalous, negative behaviour. At higher fields and temperatures, the magnetoresistance exhibits a more conventional, positive curvature with increasing field strength. As a possible explanation, we propose carrier scattering at localised magnetic trace impurities and magnetic correlations.

“…Field and temperature dependences of the magnetization in the magnetic field below 5 T were measured by using SQUID magnetometer (Quantum Design). Experiments in magnetic fields up to 50 T were conducted at KULeuven pulsed field facility [21] (Belgium). In all cases, the magnetic field was aligned along [110] direction.…”

Magnetic properties of single crystals of Mn1−xFexSi solid solutions with x < 0.2 are investigated by pulsed field technique in magnetic fields up to 50 T. It is shown that magnetization of Mn1−xFexSi in the paramagnetic phase follows power law M (B) ∼ B α with the exponents α ∼ 0.33 − 0.5, which starts above characteristic fields Bc ∼ 1.5−7 T depending on the sample composition and lasts up to highest used magnetic field. Analysis of magnetization data including SQUID measurements in magnetic fields below 5 T suggests that this anomalous behavior may be likely attributed to the formation of a field-induced Griffiths phase in the presence of spin-polaron effects.
