Superconducting phenomena in systems with unconventional magnets

Area of Science:

• Condensed Matter Physics
• Quantum Materials Science
• Superconductivity

Background:

• Conventional magnets (ferromagnets, antiferromagnets) break time-reversal symmetry.
• Unconventional magnets (UMs) possess properties of both ferromagnets and antiferromagnets, including zero net magnetization and spin-split bands.
• UMs exhibit anisotropic spin-polarized Fermi surfaces and momentum-dependent magnetic order (e.g., d-wave altermagnets, p-wave magnets).

Purpose of the Study:

• To comprehensively review recent advances in superconductivity involving unconventional magnets (UMs).
• To focus on emerging superconducting phenomena at superconductor-UM interfaces.
• To discuss potential quantum applications arising from these interactions.

Main Methods:

• Literature review of recent experimental and theoretical studies.
• Analysis of superconducting phenomena in junctions with UMs.
• Discussion of material properties and their impact on superconductivity.

Main Results:

• Superconductivity in junctions with UMs is a rapidly developing field.
• UMs, such as d-wave altermagnets and p-wave magnets, introduce novel physics to superconductor heterostructures.
• The interplay between UMs and superconductivity leads to unique phenomena not observed with conventional magnets.

Conclusions:

• The combination of UMs and superconductors offers a promising platform for exploring new quantum phenomena.
• Further research into these systems could unlock significant advancements in quantum technologies.
• This review highlights the critical progress and future directions in the field.
