Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks

F. Freund, D. Sornette

We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the c…

Incommensurate Counterrotating Magnetic Order Stabilized by Kitaev Interactions in the Layered Honeycomb $I^\pm$ -Li $_{2}$ IrO $_{3}$

S. C. Williams, R. D. Johnson, F. Freund +8

The layered honeycomb magnet $I^\pm$ -Li $_{2}$ IrO $_{3}$ has been theoretically proposed as a candidate to display novel magnetic behaviour associated with Kitaev interactions between spin-…

Pressure-induced formation of rhodium zigzag chains in the honeycomb rhodate Li $_{2}$ RhO $_{3}$

V. Hermann, S. Biswas, J. Ebad-Allah +8

We use powder x-ray diffraction to study the effect of pressure on the crystal structure of the honeycomb rhodate Li $_{2}$ RhO $_{3}$ . We observe low-pressure ( $P$ $<$ $P_{c 1}$ = 6.5 GPa)…

Breakdown of magnetic order in the pressurized Kitaev iridate $I^^{2}$ -Li $_{2}$ IrO $_{3}$

M. Majumder, R. S. Manna, G. Simutis +14

Temperature-pressure phase diagram of the Kitaev hyperhoneycomb iridate $I^^{2}$ -Li $_{2}$ IrO $_{3}$ is explored using magnetization, thermal expansion, magnetostriction, and muon spin rotat…

Unconventional magnetic order on the hyperhoneycomb Kitaev lattice in $I^^{2}$ -Li2IrO3: full solution via magnetic resonant x-ray diffraction

A. Biffin, R. D. Johnson, Sungkyun Choi +6

The recently-synthesized iridate $I^^{2}$ -Li $_{2}$ IrO $_{3}$ has been proposed as a candidate to display novel magnetic behavior stabilized by frustration effects from bond-dependent, aniso…

High-pressure versus isoelectronic doping effect on the honeycomb iridate Na $_{2}$ IrO $_{3}$

V. Hermann, J. Ebad-Allah, F. Freund +7

We study the effect of isoelectronic doping and external pressure in tuning the ground state of the honeycomb iridate Na $_{2}$ IrO $_{3}$ by combining optical spectroscopy with synchrotr…
