The quest for lossless electricity transmission has taken a major step forward. An international team of researchers, including scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), has successfully used nuclear magnetic resonance (NMR) spectroscopy to study lanthanum superhydrides under extreme pressure for the first time, revealing valuable insights into one of the world's most promising superconducting materials.

Superconductors can carry electricity with zero resistance, eliminating energy losses during transmission. However, most known superconductors only work at extremely low temperatures, making them costly and difficult to use in everyday applications. Scientists have long searched for materials capable of superconducting at much higher temperatures.

Among the most exciting candidates are superhydrides—hydrogen-rich compounds that display extraordinary properties when subjected to immense pressures. Lanthanum superhydrides, in particular, have attracted global attention because they have demonstrated superconducting behavior at temperatures approaching room temperature, setting records for the highest known superconducting transition temperatures. Figure 1 shows Superconductors.

A New Window into Extreme Materials

Studying these materials is exceptionally challenging. Researchers must compress tiny samples between diamond anvils at pressures exceeding one million atmospheres, recreating conditions similar to those found deep inside giant planets.

To overcome this challenge, the team employed microscopic devices known as Lenz lenses. Acting like magnetic superlenses, these tiny conductive rings focus and amplify the high-frequency signals required for NMR measurements directly into the microscopic sample area.

This innovative approach allowed scientists to collect meaningful atomic-scale data from superhydrides for the first time, offering an unprecedented view of their internal structure and behavior.

Combining Pressure and Magnetic Fields

The researchers complemented their NMR investigations with experiments using some of the world's strongest pulsed magnetic fields. These measurements help determine how much magnetic stress a superconductor can withstand before losing its superconducting properties.

Together, high-pressure NMR analysis and high-field resistance testing provide a much more complete picture of how these remarkable materials function under extreme conditions.

Toward the Future of Energy Technology

The breakthrough was made possible through collaboration between HZDR scientists and high-pressure experts at the Center for High Pressure Science & Technology Advanced Research (HPSTAR) in Beijing [1]. By combining advanced instrumentation, high magnetic fields, and innovative experimental techniques, the team has opened a new path for exploring superconducting materials at the atomic level.

Researchers hope that understanding the fundamental mechanisms behind hydrogen-rich superconductors will eventually lead to the development of practical, high-temperature superconductors. Such materials could transform power transmission, energy storage, transportation, and many other technologies by enabling electricity to flow without loss and with far greater efficiency than ever before.
