Single femtosecond laser pulse excitation of individual cobalt nanoparticles
Tatiana M. Savchenko, Michele Buzzi, Ludovic Howald +12
Laser-induced manipulation of magnetism at the nanoscale is a rapidly growing research topic with potential for applications in spintronics. In this work, we address the role of th…
Superconductivity drives magnetism in delta-doped La2CuO4
A. Suter, G. Logvenov, A. V. Boris +7
The understanding of the interplay between different orders in a solid is a key challenge in highly correlated electronic systems. In real systems this is even more difficult since…

Ludovic Howald
This comment clarifies the mixed definition of the cerium valence in the article entitled: Quantitative study of the occupation in CeMIn5 and other cerium compounds with hard X…
Evidence for Coexistence of Bulk Superconductivity and Itinerant Antiferromagnetism in the Heavy Fermion System CeCo(InCd)
Ludovic Howald, Evelyn Stilp, Pierre Dalmas de Réotier +6
In the generic phase diagram of heavy fermion systems, tuning an external parameter such as hydrostatic or chemical pressure modifies the superconducting transition temperature. Th…
Multigap Superconductivity in the Ferromagnetic Superconductor UCoGe Revealed by Thermal Conductivity Measurements
Ludovic Howald, Mathieu Taupin, Dai Aoki
We performed thermal conductivity measurements on a single crystal of the ferromagnetic superconductorUCoGe under magnetic field. Two different temperature dependencies of the ther…

L. Howald, A. Maisuradze, P. Dalmas de Réotier +6
In the tetragonal heavy fermion system CeCoIn5 the unconventional superconducting state is probed by means of muon spin rotation. The pressure dependence (0-1 GPa) of the basal-pla…
Muon-spin rotation and magnetization studies of chemical and hydrostatic pressure effects in EuFe_{2}(As_{1-x}P_{x})_{2}
Z. Guguchia, A. Shengelaya, A. Maisuradze +7
The magnetic phase diagram of EuFe(AsP) was investigated by means of magnetization and muon-spin rotation studies as a function of chemical (isovalent sub…
Field-induced Phenomena in Ferromagnetic Superconductors UCoGe and URhGe
Dai Aoki, Mathieu Taupin, Carley Paulsen +13
We review our recent studies on ferromagnetic superconductors, UGe2, URhGe and UCoGe, where the spin-triplet state with the so-called equal spin pairing is realized. We focus on ex…
Thermoelectricity of the Ferromagnetic Superconductor UCoGe
Liam Malone, Ludovic Howald, Alexandre Pourret +4
UCoGe exhibits superconductivity in the presence of ferromagnetism. When a field is applied along the b axis (perpendicular to the easy axis), ferromagnetism is weakened and superc…
Upper critical field of CeCoIn5
Ludovic Howald, Georg Knebel, Dai Aoki +2
We present a detailed analysis of the upper critical field for CeCoIn5 under high pressure. We show that, consistently with other measurements, this system shows a decoupling betwe…
