Journal ArticleDOI
Programmable computing with a single magnetoresistive element
TL;DR: A simple hardware concept for a programmable logic element that is based on a single magnetic random access memory (MRAM) cell that combines the inherent advantage of a non-volatile output with flexible functionality which can be selected at run-time to operate as an AND, OR, NAND or NOR gate.
Journal ArticleDOI
Absence of intrinsic ferromagnetic interactions of isolated and paired Co dopant atoms in Zn1-xCoxO with high structural perfection.

TL;DR: The total magnetization is reduced by approximately 30%, demonstrating that Co-O-Co pairs are antiferromagnetically coupled and no sign of intrinsic ferromagnetic interactions for isolated or paired Co dopant atoms in Co:ZnO films is found.
Journal ArticleDOI
Large magnetic gap at the Dirac point in Bi2Te3/MnBi2Te4 heterostructures.

TL;DR: The anomalous quantum Hall effect is observed in edge channels of topological insulators when there is a magnetic energy gap at the Dirac point; this gap has now been observed by low-temperature photoelectron spectroscopy in Mn-doped Bi2Te3.
Journal ArticleDOI
Sensitive SQUID magnetometry for studying nanomagnetism
TL;DR: In this article, a detailed discussion of possible artifacts and pitfalls characteristic for commercial superconducting quantum interference devices (SQUID magnetometers) is presented, which includes intrinsic artifacts which stem from the inherent design of the magnetometer as well as potential issues due to the user.

Sensitive SQUID magnetometry for studying nano-magnetism
TL;DR: In this paper, a detailed discussion of possible artifacts and pitfalls characteristic for commercial superconducting quantum interference devices (SQUID magnetometers) is presented, which includes intrinsic artifacts which stem from the inherent design of the magnetometer as well as potential issues due to the user.
