We establish the sign of the linear magnetoelectric (ME) coefficient, $\alpha$, in chromia, Cr$_2$O$_3$. Cr$_2$O$_3$ is the prototypical linear ME material, in which an electric (magnetic) field induces a linearly proportional magnetization (polariza

The PanEDM neutron electric dipole moment experiment at the ILL

Publikováno v: EPJ Web of Conferences, Vol 219, p 02006 (2019)

The neutron's permanent electric dipole moment dn is constrained to below 3 × 10−26e cm (90% C.L.) [1, 2], by experiments using ultracold neutrons (UCN). We plan to improve this limit by an order of magnitude or more with PanEDM, the first experim

Skyrmions and spirals in MnSi under hydrostatic pressure

Autor: Bannenberg, Lars J., Sadykov, Ravil, Dalgliesh, Robbert M., Goodway, Chris, Schlagel, Deborah L., Lograsso, Thomas A., Falus, Peter, Lelièvre-Berna, Eddy, Leonov, Andrey O., Pappas, Catherine

Publikováno v: Physical Review B 100 (5), 054447 (2019)

The archetype cubic chiral magnet MnSi is home to some of the most fascinating states in condensed matter such as skyrmions and a non-Fermi liquid behavior in conjunction with a topological Hall effect under hydrostatic pressure. Using small angle ne

40-tesla pulsed-field cryomagnet for single crystal neutron diffraction

Autor: Duc, Fabienne, Tonon, Xavier, Billette, Julien, Rollet, Bertrand, Knafo, William, Bourdarot, Frédéric, Béard, Jérome, Mantegazza, Frédéric, Longuet, Benjamin, Lorenzo, Jose-Emilio, Lelièvre-Berna, Eddy, Frings, Paul, Regnault, Louis-Pierre

Publikováno v: Review of Scientific Instruments, Volume 89, Issue 5, 053905 (2018)

We present the first long-duration and high duty cycle 40-tesla pulsed-field cryomagnet addressed to single crystal neutron diffraction experiments at temperatures down to 2 K. The magnet produces a horizontal field in a bi-conical geometry, $\pm$15

High-pressure cell for simultaneous dielectric and neutron spectroscopy

Autor: Sanz, Alejandro, Hansen, Henriette Wase, Jakobsen, Bo, Pedersen, Ib H., Capaccioli, Simone, Adrjanowicz, Karolina, Paluch, Marian, Gonthier, Julien, Frick, Bernhard, Lelièvre-Berna, Eddy, Peters, Judith, Niss, Kristine

In this article we report on the design, manufacture and testing of a high-pressure cell for doing simultaneous dielectric and neutron spectroscopy. This cell is a unique tool for studying dynamics on different timescales, from kilo- to picoseconds,
