Magnonic crystals with reconfigurable magnetic defects for spin-based microwave electronics

Korbinian Baumgärtl

Collective spin excitations can propagate in magnetically ordered materials in the form of waves. These so-called spin waves (SWs) or magnons are promising for low-power beyond-CMOS information processing, which does not rely anymore on the lossy movement ...

Combined synchrotron x-ray diffraction and NV diamond magnetic microscopy measurements at high pressure

Mayeul Sylvain Chipaux, Charles Michel Henri Pépin, Margarita Lesik Gaussens

We report the possibility to simultaneously perform wide-field nitrogen-vacancy (NV) diamond magnetic microscopy and synchrotron x-ray diffraction measurements at high pressure. NV color centers are created on the culet of a diamond anvil which is integrat ...

Emergent bound states and impurity pairs in chemically doped Shastry-Sutherland system

Frédéric Mila

Impurities often play a defining role in the ground states of frustrated quantum magnets. Studies of their effects are crucial in understanding of the phase diagram in these materials. SrCu2(BO3)(2), an experimental realization of the Shastry-Sutherland (S ...

Neel-like domain walls in ferroelectric Pb(Zr,Ti)O-3 single crystals

Nava Setter, Tomas Sluka

In contrast to the flexible rotation of magnetization direction in ferromagnets, the spontaneous polarization in ferroelectric materials is highly confined along the symmetry-allowed directions. Accordingly, chirality at ferroelectric domain walls was trea ...

Semiclassical theory of the magnetization process of the triangular lattice Heisenberg model

Frédéric Mila, Tommaso Coletta

Motivated by the numerous examples of 1/3 magnetization plateaux in the triangular-lattice Heisenberg antiferromagnet with spins ranging from 1/2 to 5/2, we revisit the semiclassical calculation of the magnetization curve of that model, with the aim of com ...

Unconventional mechanisms of magnetic ordering in frustrated models of quantum magnetism

Tommaso Coletta

In this thesis we investigate in the semiclassical approximation how unconventional magnetic ordering, that is magnetic ordering which is not predicted at the classical level, emerges in a variety of frustrated models of quantum magnetism. The first part o ...

Growth and Magnetism of Nanostructures Investigated by STM, MOKE, and XMCD

Alberto Cavallin

This thesis presents our studies on nanostructures growth and magnetism, mainly based on scanning tunneling microscopy (STM), magneto-optical Kerr effect (MOKE), and x-ray magnetic circular dichroism (XMCD) measurements. In most of these experiments, nanos ...

Magnetization of SrCu2(BO3)(2) in Ultrahigh Magnetic Fields up to 118 T

Frédéric Mila

The magnetization process of the orthogonal-dimer antiferromagnet SrCu2(BO3)(2) is investigated in high magnetic fields of up to 118 T. A 1/2 plateau is clearly observed in the field range 84 to 108 T in addition to 1/8, 1/4, and 1/3 plateaus at lower fiel ...

Unconventional magnetization plateaus in a Shastry-Sutherland spin tube

Frédéric Mila, Jean-David Picon

Using density matrix renormalization group (DMRG) and perturbative continuous unitary transformations (PCUTs), we study the magnetization process in a magnetic field for all coupling strengths of a quasi-1D version of the 2D Shastry-Sutherland lattice, a f ...

Magnetization plateaux in an extended Shastry-Sutherland model

Frédéric Mila, Julien Dorier

We study an extended two-dimensional Shastry-Sutherland model in a magnetic field where besides the usual Heisenberg exchanges of the Shastry-Sutherland model two additional SU(2) invariant couplings are included. Perturbative continous unitary transformat ...
