Anomalous Hall Effect due to Magnetic Fluctuations in a Ferromagnetic Weyl Semimetal

The anomalous Hall effect (AHE) has emerged as a key indicator of time-reversal symmetry breaking (TRSB) and topological features in electronic band structures. Absent of a magnetic field, the AHE requires spontaneous TRSB but has proven hard to probe due to averaging over domains. The anomalous component of the Hall effect is thus frequently derived from extrapolating the magnetic field dependence of the Hall response. We show ....

Two Characteristic Contributions to the Superconducting State of 2H-NbSe2

Multiband superconductivity arises when multiple electronic bands contribute to the formation of the superconducting state, allowing distinct pairing interactions and gap structures. Here, we present field- and temperature-dependent data  ...

Observation of the spiral spin liquid in a triangular-lattice material

The spiral spin liquid (SSL) is a highly degenerate state characterized by a continuous contour or surface in reciprocal space spanned by a spiral propagation vector. Although the SSL state has been predicted in a number of various theoretical models, very few materials are so far experimentally identified to host such a state. Via combined single-crystal wide-angle and small-angle neutron scattering, we report observation  ...

Pressure-enhanced splitting of density wave transitions in La3Ni2O7–δ

The observation of superconductivity in La3Ni2O7–δ under pressure, following the suppression of a high-temperature density wave state, has attracted considerable attention. The nature of this density wave order was not clearly identified. Here we probe the magnetic response of the zero-pressure phase of La3Ni2O7–δ as hydrostatic pressure is applied, and find that the apparent single density wave transition at zero applied pressure splits into two. The comparison of our muon-spin rotation ...

Spin-orbit control of antiferromagnetic domains without a Zeeman coupling

Encoding information in antiferromagnetic (AFM) domains is a promising solution for the ever growing demand in magnetic storage capacity. The absence of a macroscopic magnetization avoids crosstalk between different domain states, enabling ultrahigh density spintronics while being detrimental to the domain detection and manipulation. Disentangling these merits and disadvantages seemed so far unattainable. We report evidence ...

300

The CNM center hosts 300 members of staff, in addition 40 PhD students perform their thesis work within CNM

5+1

The center is organized in 5 laboratories and 1 staff group.

3/30

CNM operates 3 of the 5 large scale user facilities: the Swiss spallation neutron source SINQ, the Swiss Muon Source SμS and the facilities for particle physics CHIRSP with approximately 30 experimental stations open for users.

1700

The facilities in the CNM center are open to international access — with approximately 1700 annual user visits the associated user program is a key activity for the center and for PSI as a whole.
