Unveiling complex magnetic interactions in RE2In (RE = Nd, Pr) compounds by neutron diffraction

Karthika K. Thilakan, Wei Liu, Přemysl Beran, Dennis Cheptyakov et autres

The magnetic structures and the nature of the magnetic phase transitions in Nd2In and Pr2In were investigated using neutron powder diffraction in combination with magnetometry. M(T) curves for both compounds exhibit two distinct step-wise ferromagnetic (FM)-like transitions: at 110 K (TC1) and …

Unraveling the symmetry of Al5C3N

Vitalii Shtender, Chin Shen Ong, P. Berastegui, Olivier Donzel‐Gargand et autres

The high-temperature ceramic compound Al5C3N with promising application usage belongs to the scarcely studied Al-C-N system. It was originally reported as an ordered compound in the non-centrosymmetric space group P63mc and described as a nanolaminate with an -Al2C-AlN-Al2C2- stacking sequence. The recently …

A comparison of the spin-phonon behaviour of Fe$_2$P-based magnetocaloric materials

Mikael Svante Andersson, Simon Rosenqvist Larsen, Erna Krisztina Delczeg-Czirjak, Antonio Corona et autres

Magnetic refrigeration can provide an environmentally friendly technology to reduce significantly the energy consumption of cooling devices. To retain the sustainability of the device, all parts must be made from abundant materials, excluding e.g. rare earth elements. As such, materials based on …

Crystal-chemical controls on the magnetic behavior of REE-bearing minerals

Julia Sordyl, Antonio Corona, Bjarne Almqvist, Dan Holtstam et autres

Magnetic properties of ferrimagnetic minerals have been studied in detail over the years. By contrast, the magnetic properties of paramagnetic minerals containing rare earth elements (REE) remain largely unexplored, even though the presence of particular rare-earth ions can give rise to complex …

Triphasic Inter‐Dimensional WS 2 /Magnetic Lithium Iron Oxide Nanocomposite for Electromagnetic Interference Shielding

Sagnik Ghosh, Mustafa Aboulsaad, Sawssen Slimani, Johan Cedervall et autres

Abstract The widespread use of wireless devices and telecommunication networks has given rise to electromagnetic interference (EMI) pollution that can cause data corruption, critical device failure, and detrimental effects on wildlife and human health. Developing EMI shielding materials can block these harmful …

Deciphering Transition Metal Diffusion in Anode Battery Materials: A Study on Nb Diffusion in NbxTi1−xO2

Ola Kenji Forslund, Carmen Cavallo, Johan Cedervall, Jun Sugiyama et autres

ABSTRACT Demand for fast‐charging lithium‐ion batteries (LIBs) has escalated incredibly in the past few years. A conventional method to improve the performance is to chemically partly substitute the transition metal with another to increase its conductivity. In this study, we have chosen …

Revealing complex magnetic interactions in Fe 2 P-based compounds: a study using Mössbauer spectroscopy and neutron diffraction

Karthika K. Thilakan, Sagar Ghorai, Lennart Häggström, Fredrik Lindgren et autres

In Fe 2−2 x Mn 2 x P 1− x Si x , the magnetic properties have 4 different regions out of which 3 have ferromagnetic character. In region (ii), a glassy magnetic behaviour is found with an incommensurate ordering, exemplified with …

Biphasic lithium iron oxide nanocomposites for enhancement in electromagnetic interference shielding properties

Sagnik Ghosh, Pramod K. B. Rangaiah, Mustafa Aboulsaad, Sawssen Slimani et autres

There is a great demand for efficient electromagnetic interference (EMI) shielding materials due to exponential growth in wireless telecommunication devices. These devices emit electromagnetic radiation that can disrupt electronic devices, and cause health hazards. Therefore, it is crucial to develop materials that …
