The influence of the incommensurately modulated structure on the physical properties of Fe1.35Ge

Helmuth Berger, László Forró, Alla Arakcheeva, Philip Pattison, Krunoslav Prsa, Jacim Jacimovic, Sergiy Katrych, Andrea Pisoni

Single crystal growth by chemical vapour transport has resulted samples with Fe1.35Ge stoichiometry. Structural study has shown that the large number of vacancies introduces an incommensuately modulated structure. The electrical resistivity is in the 200 m ...

Growth of CNT Forests on Titanium Based Layers, Detailed Study of Catalysts

László Forró, Klara Hernadi, Endre Horvath, Pavao Roko Andricevic

For better electrical contacts of potential devices, growth of vertically aligned carbon nanotubes (CNT forests) directly onto conductive substrates is an emerging challenge. Here, we report a systematic study on the CCVD synthesis of carbon nanotube fores ...

J1-J2 square lattice antiferromagnetism in the orbitally quenched insulator MoOPO4

Helmuth Berger, László Forró, Arnaud Magrez, Oleg Yazyev, Bálint Náfrádi, Henrik Moodysson Rønnow, Ivica Zivkovic, Peter Babkevich, Lin Yang, Noore Elahi Shaik

We report magnetic and thermodynamic properties of a 4d1 (Mo5+) magnetic insulator MoOPO4 single crystal, which realizes a J1−J2 Heisenberg spin-1/2 model on a stacked square lattice. The specific-heat measurements show a magnetic transition at 16 K which ...
